for that to make sense, you'd have to think that republicans dont' believe that their support will bring either corporate campaign contributions or latino votes in 2014.
I don't know if they can put it off that long. The Senate has already passed an immigration bill. The more moderate (less radical?) House Republicans know that they need to at least make a token offer of legislation, but the mainstream (more radical) members of the House Republican caucus are champing at the bit to offer up their "Death to all Mexicans" amendments. It should be interesting.
